4. NCB connection
Via the Network Control Bus system several routers and control panels can be interconnected.
The standard MIDI interface is used on all NCB control ports. The BRS-3232 router utilises RJ45
connectors for connecting to the NCB. However, for interconnection between the other Triton devices a
standard MIDI cable with 5pin DIN connector on both ends is used. This means that when you connect
your BRS-3232 router to other Triton devices, with MIDI connectors, an RJ45/MIDI interface is
necessary. This converter can be ordered from Thomson Grass Valley.
The NCB system allows connection of up to 16 routers with different levels on the same bus. Control
panels dedicated to work with a specific router must be configured to the same level as the router. Several
panels can work together with one specific router. Up to 16 single routers or combinations of routers can
be controlled from the Triton - Router Control System. The NCB system and all RS-232 ports interchange
the system status.
4.1. Several routers in one system
The NCB system allows the interconnection of up to 16 routers with different levels in one system. A
combination of routers working married counts as one level. This might for example be 1 audio router + 1
video router working as an audio follows video system or 3 video routers working as an RGB (YUV)
system. The routers in such a constellation must be configured to the same level.
4.2. Connecting control panels
To get a control panel working with a specific router, configure the control panel to the same level as the
router. Several panels can be configured to control the same router. The Triton panels can control 2 levels
with breakaway function. If it is necessary to control more levels with breakaway an additional panel must
be used. Panels can also be connected to a router via the RS-232 interface. Please refer to your
control panel manual for installation.
